/*QUAKED func_breakaway (0 .5 .8) ? Trigger_Spawn Animated Animated_Fast Inactive Fade AlwaysShoot TargAngle
Any brush model that you want to break away from its surroundings (masonry, boulders, etc.).
Needs an origin brush unless its center is at the map origin.

If targeted it will not be shootable, unless the inactive flag is set.

Inactive -	Specifies that the entity is not shootable until triggered.
Fade -		Specifies that the entity will fade away after coming to a rest.
				Time to fade is specified by "fadeout".  Default: 30 seconds.
AlwaysShoot-	Damagable even if targeted.
TargAngle-		Will rotate toward "move_angles" when dislodged.  Useful for objects that fall over flat.  Use "duration" for how many seconds the rotation takes.  Default: 5, will also always be > "wait"

"health"	Defaults to 100.
"health2"	How much health to destroy the brush after it has come to a stop.
"mass"		Defaults to 500.  This determines how much damage the falling boulder does.
"speed"		Defaults to 100.  This sets how fast the brush will move (only if triggered).
"angles"	Sets the initial angle that the brush will move at.  Use pitch, yaw, and roll.
"delay"		How long to wait before breaking away, default 0.
"wait"		How long before it becomes SOLID_BBOX after being dislodged, default 0.3.
"fadeout"	If the Fade flag is set, this is how long until it fades away.
"noise"		Sound to play when it hits.
"count"		Number of times to play impact sound

"target"	Will fire all entities with this targetname when it breaks free.
"deathtarget"	Will fire all entities with this targetname when it breaks free.
"destroytarget"	Will fire all entities with this targetname when it is destroyed after coming to a rest.

"gib_type"	Set to 1 for metal, 2 for glass, 3 for barrel, 4 for crate, 5 for rock, 6 for crystal
			7 for mechanical, 8 for wood, 9 for tech gibs.

"bleft"		Min b-box coords XYZ. Default = -16 -16 -16
"tright"	Max b-box coords XYZ. Default = 16 16 16

To have other entities move with the brush, set the door pieces' movewith values to the same as the brush's targetname and they will move in
unison, and will also fade away in unison if the Fade spawnflag is set.  Be sure to use the AlwaysShoot spawnflag if you want it to be shootable.
NOTE: All the pieces must be created after the brush entity, otherwise they will move ahead of it.
